Creator Appreciation Percentage is the percentage share that a creator receives of the appreciated value of the NFT on all future sales. It is different from traditional royalties where creators receive a percentage share on the total sale.
Here are some examples of how Creator Appreciation of 20% works:
First sale, Jane creates and sells for $10 to Luna.
Luna sells to Ben for $11, Jane gets 20% of $1, or 20 cents.
Ben sells to Ron for $10, Jane gets nothing.
Ben sells to Harry for $100, Jane gets 20% of $89, or $17.8.
